The geometric mean is always greater than or equal to the harmonic mean for any set of positive numbers. This relationship is a result of the Cauchy-Schwarz inequality. In cases where all numbers in the set are equal, both means will be the same; otherwise, the geometric mean will exceed the harmonic mean.
To calculate the geometric mean for grouped data, use the formula ( GM = e^{(\sum (f \cdot \ln(x))) / N} ), where ( f ) is the frequency, ( x ) is the midpoint of each class interval, and ( N ) is the total frequency. For the harmonic mean, use the formula ( HM = \frac{N}{\sum (f / x)} ), where ( N ) is the total frequency and ( x ) is again the midpoint of each class interval. Both means provide insights into the central tendency of the data, with the geometric mean suitable for multiplicative processes and the harmonic mean for rates.
The advantage of harmonic mean is that it is used to solve situations in which there are extreme data values to true picture. The disadvantage of it is that it can be time consuming to evaluate the data.
A body undergoes simple harmonic motion if the acceleration of the particle is proportional to the displacement of the particle from the mean position and the acceleration is always directed towards that mean. Provided the amplitude is small, a swing is an example of simple harmonic motion.
The arithmetic mean, geometric mean and the harmonic mean are three example of averages.
When applied to electrical waveforms, a 'harmonic' is a multiple of the fundamental frequency.

A minor harmonic progression typically includes the use of the minor scale, minor chords, and the harmonic minor scale. Common patterns found in minor harmonic progressions include the use of the i, iv, and V chords, as well as the use of leading tones to create tension and resolution.

If x and y are two positive numbers, with arithmetic mean A, geometric mean G and harmonic mean H, then A ≥ G ≥ H with equality only when x = y.
